Basic description

High durability and operational reliability were the decisive criteria in the development of the new H7 telemetry and control unit. For these reasons, the unit is housed in a rugged cast aluminum along with a backup power supply battery and input terminals for connecting sensors and transducers. High IP67 protection also has a USB connector and built-in GSM / GPRS or Wi-Fi communication module (for H7-G or H7-W telemetry stations).

Datalogger H7 contains many above-standard self-diagnostic procedures from measuring humidity inside the device through various control channels monitoring voltages and currents flowing to connected sensors and sensors, to integrative measurement of energy consumed from the battery.

The large color touch screen and fingerboard keyboard together with the clear MENU contribute to easy intuitive operation of the device.

Several variants of lockable cabinets are available for the installation of the H7 unit in the field, including mounting brackets and masts.

Datahosting

Datahosting FIEDLER

 

Telemetry stations H7-G, H7-W use data hosting set up on the manufacturer's server. The user does not have to set up his own server or ensure its operation and maintenance. Authorized users can access the data stored on the server at any time via a standard web browser.

In addition to graphical and tabular visualization, the server also enables statistical calculations of balance flows, searching for limit values, data exports in several formats to FTP servers or to the PC of a logged-in client, printing monthly balance reports, sending e-mails and some other functions.

Basic functions and features

Analog recording channels - datalogger function

Up to 96 analog channels for recording the value of the measured quantity. Each channel can be set with its specific name, number of decimal places for archiving, measurement method, limit values ​​for alarms and many other parameters.

There are preset units for level, flow, volume, temperature, RH, pH, redox, diss. oxygen, conductivity, pressure, rainfall, current, voltage, pulses, radiation and other physical quantities. The measurement is performed by an accurate 24-bit converter, adjustable resolution of the measured quantity: 0 to 3 decimal places.

The archiving interval is adjustable from 1 s to 24 h separately for each recording channel. Datalogger H7 supports the transition to more frequent measurements and recording of selected quantities after exceeding a limit value (limit alarm) or after a quick change of value (gradient alarm) and also allows to set delayed measurements for sensors that require a longer rise time from power on.

Binary recording channels

Datalogger H7 contains up to 208 binary channels. Each channel is configurable as a binary input or binary output (ON / OFF).
The input binary channel records the moment of switching on and off of the input with a time resolution of 1 s (runs and faults, security vol., ...). Output binary channels allow to command relays based on logic functions with other binary channels (AND, NAND, OR, NOR, XOR).

Text channel - diary of events

Sending data to the server, texts and phone numbers of received and sent SMS, faults of connected sensors, power failures, ...

Unit control and above-standard functions

  • Clear intuitive MENU - several language versions
  • Choice of different types of single-channel and multi-channel graphs
  • Overview graphs from archived values
  • Search for daily lows, highs and elapsed volumes
  • Computational functions over measuring channels (sum, moving sum or average, difference, trend, correction by 2nd order polynomial) with output to a separate channel and to SMS
  • Control of the sampling device in 4 operating modes
  • Limit and gradient alarms for each analog channel.

Recording and monitoring of pulse water meters flow

  • 64 recording channels with support for calculation and archiving of daily, monthly and annual flow volumes.
  • Calculation of instantaneous flow from pulses (REED and OPTO sensors).

Flow measurement in open profiles

  • 4 recording channels for measuring and calculating flows and flow volumes using consumption equations.
  • Preset 16 equations for the most common Parshall troughs and specific overflows. User-adjustable parameters of the general consumption equation also for compound gutters and tabular input Q = f (H).
  • Each flow meter is assigned a counter of operating hours and the total time of non-functional flow measurement (time in fault).

Outputs

  • Limit, time and logic control of own and external relays
  • 4 adjustable controllers with mode selection - PID or hysteresis controller, pulse valve.
  • Recording the status of the controller in a binary channel.
  • Interlock and shift function for controlling two or three pumps.

GPRS (telemetry station)

  • Automatic sending of data to the server at regular intervals.

  • Sending data directly to email or FTP server (daily reports)
  • Direct GPRS communication between stations
  • Universal command (XML, JSON, etc.).
  • Symmetric cipher for transmitted files (commands and data)
  • H7 parameterization and FW upgrade via server. Backup of current parameter files on the server.

System of warning, informative and control SMS:

  • Telephone directory for 48 recipients, grouping into 3 groups.
  • 48 adjustable warning SMS messages (any text, automatic insertion of the current value, various trigger conditions including their duration, hysteresis, ...).
  • Informative SMS compiled on the basis of a command line or query SMS (actual values, max, min, balance, operating hours, ...).
  • Command SMS for control and simulation of outputs (binary and analog), setting of selected coefficients and parameters, forced sending of data to the server, ...).
